CULTIVATOFL SPECIFICATION forming part of Letters Patent No. 780,430,dated January 17, 1905.

- Application filed July 1,1904. serial No. 214,943.

To cir/ZZ whom, t may concern:

Be it vknown that I, FRANK KREss, a citizen of the United States,residing at Pisgah, in the county of Harrison and State of Iowa, haveinvented new and useful Improvements in Cultivators, of which thefollowing is a specification.

This invention relates to cultivators, .the object of the inventionbeing to provide what may be termed anv attachment for cultivators bymeans of which the cultivator as a whole is adapted to sidehill plowingor cultivating as well as operating upon level ground, the primaryobject of the invention being to provide, in connection with the beam orframe of a riding or walking cultivator, a shovel and standard, thelatter of which has a jointed connectionwith such beam or frame and isoperatively coupled to a hand-lever by means of which the point of theshovel may be raised and lowered for the purpose of regulating the depthof penetration of the shovel. means described one shovel may be setlower or higher than the adjoining shovel, so that in sidehill work bothshovels will operate at substantially the same depthfin the soil.

A further object of the invention is to so mount said shovel and theoperatingmechanism therefor that the said shovel may quickly and easilybe adjusted by the operator without stopping the machine and asfrequently as may be necessary owing to the varying slope or angle ofthe hill being worked.

Wit-h the above and other objects in view the invention consists in thenovel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed.

The vaccompanying drawing represents a perspective view `of a cultivatorembodying the present invention.

In the drawing I have represented a simple form of cultivator embodyingthe usual frame or beam 1, provided withl handle-bars 2 and handles 3and clevis 41. Extending downward from the beam lat a suitable 'point isa fixed standard 5, to the lower end of which is connected a shovel 6 ofany desired type, while the fixed standard 5 is connected by a forwardlyand upwardly inclining brace7 with opposite end lto the adjustablestandard 8.

ing pivotally connected to its lower arm a draftlink 141, which connectspivotally at its It will be noticed that the lixed standard 5 isconnected to one sideofthe frame or beam 1, while the adjustablestandard is connected to the opposite side, so that said standards arelaterally-offset from each other to work in different but parallelplanes. Ordinarily the standards 5 and 8 will be of the same length andset at the same angle in working on level ground. In operating' on asidehill, however', in order to have the vshovels operate at a uniformdepth in the soil the standard 8 will be swung forward or backward bymeans of the thumb-latch lever 11, which through the connectionsdescribed has the effect of raising or lowering the shovel 10, and thuscompensating for the pitch-or slope of the ground onk the sidehill.

By the means above described the movable shovel may be quickly adjustedwithout stopping the cultivator and without the use of anyv grasp thethumb-latch lever and throw the same tools, the operator simply being'required to one way or the other. Both shovels may be made to operate atthe same depth in the soil, and the device as a whole may be applied toand used in connection with any form of riding or walking cultivator.

I am aware that it is not broadly new to ad- My invention resides injust the shovels of a plow or cultivator in a i vertical direction, andI disclaim this con-v -struction broadly.

IOO

a fixed standard on on`e side thereof, a shovel on the fixed standard, amovable standard pivotally connected at its upper end to the beam on theside thereof opposite the fixed standard, a shovel on the movablestandard, a lever pivoted intermediate its ends tothe beam, the lowerend of said lever extending below said beam, and the upper end of saidlever extending above said beam, a draw-rod Connecting` IO the lower endor the lever Wlth the movable standard, a thumb-latch upon the lever,and a segmental rack upon the beam adapted to be engaged blv thethnnib-latoh, substantially as described.

In testimony whereof l aliix my signatnren 1 5 presence of twowitnesses.
